Magery Gains

Ok, so I've got 2 mage type chars. One is a "Pure Mage" he is set up a wizard, the other is a Swordsman with Magic.

I set up a Mana Vamp/Invisibility Macro to skill raise. Parked the Mage in the Brit Crafting Area and set to work Mana Vamping myself. In the space of an hour I gained 5 Magery points and about the same in Resist. Went from 85ish to 90ish Magery.

However, I put my Swordsman in the same place doing the same thing and after 2 hours I have had ZERO Gains. 75.3 Magery and it's stuck there. I did gain like .2 in Resist. This was after casting Invisibilty for an hour with no gains, I switched over to Mana Vamp and let it run for 2 hours.

Mana Vamp was successful about 75-80ish% of the time.

Am I doing something wrong here, is there a Power Hour on this server?
